Uber Eats double charges

I tried to lodge a complaint via the App, but I'm not getting any proper help. My account was double charged R144.70 for 3 November. The deductions took place on 7 and on 9 November. On the app, I keep getting messages that it is an authorization hold and will be reversed, but the reversal is not happening. Uber contact number *** is discontinued and the voicemail gives an email address which does not exist.
